This year's CES sucks. But that doesn't mean there can't be a few genuinely cool things floating around out there in an otherwise dull ocean of 4K and touchscreens. Case in point: YotaPhone, which sadly isn't even on the CES show floor at all. We covered the announcement of the YotaPhone, but really, seeing and using it in person does the idea so much more justice.

On paper, it seems pretty straightforward: a phone with a screen on both sides.
